The structures and processes of creative thought mirror the structures and processes of our neural networks. In creating and learning, the fundamental process is conceptual metaphor, where ideas, like neurons, connect based on matching patterns. The connections exist in clustered networks. What allows the subtle connections needed for novelty is a small amount of randomness within the linking—a...

Virtualization enables the building of multiple virtual networks over a shared substrate. One of the challenges to virtualisation is efficient resource allocation. This problem has been found to be NP hard. Therefore, most approaches to it have not only proposed static solutions, but have also made many assumptions to simplify it. In this paper, we propose a distributed, autonomic and artificia...

The outcoupling of light from thin films with a high refractive index is a problem occurring in lighting and display applications based on different technologies. Three different solutions are suggested: one-dimensional microcavity structures, roughness in the emitting layer, and roughness in the substrate/air interface. The advantages and drawbacks of these principles have to be evaluated for ...
